DESCRIPTION

The present application discloses a snorkel system and a flotation device for snorkeling. The snorkel system and flotation device are designed such that it may be used by people of all ages and swimming abilities. The system and device may also be configured for use by multiple people at the same time. Furthermore, the system and device of the present application provides the ability for the user(s) to snorkel while only being partially submerged in the water (e.g., greater than 50% of the their body remains out of the water, greater than 60% of their body remains out of the water, greater than 75% of their body remains out of the water, or greater than 85% of their body remains out of the water). This is desirable for users who do not wish to be engulfed by the water or when the water is cold.

The snorkel system of the present application generally comprises a flotation portion (e.g., a foam mat, board or inflatable) for supporting a person in a body of water and having an opening for the user's head. The opening extends through the flotation portion and is sized and configured to permit the user to put his or her face through the opening and into the water. The snorkel system also generally comprises a breathing tube having a substantially rigid first portion extending upward from the top of the flotation portion and a second flexible portion fluidly connected to a mouthpiece. The second portion is configured such that the mouthpiece is accessible to the user positioned on the top of the flotation portion and may be inserted into the person's mouth when his or her face is disposed in the opening.

FIGS. 1A and 1B illustrate a snorkel system 100 according to an embodiment of the present application. As shown, the snorkel system 100 comprises a buoyant flotation member 102 for supporting a person in a body of water and a breathing tube 104 having a substantially rigid first portion 106 in fluid communication with a flexible second portion 108.

As illustrated in Figures lA and 1B, the flotation member 102 of the snorkel system 100 comprises a top 110, a bottom 112, and at least one opening 114 extending through the flotation member from the top to the bottom. As illustrated in FIG. 1B, the opening 114 is sized and configured to permit submersion of at least a portion of the face of a person positioned on the top 110 of the flotation member 102 in the water below the bottom 112 of the flotation member. The first portion 106 of the breathing tube 104 extends upward from the top 110 of the flotation member 102 and the second portion 108 is fluidly connected to a mouthpiece 116. The second portion 108 is configured such that the mouthpiece 116 is accessible to a person positioned on the top 110 of the flotation member 102 and may be inserted into the person's mouth when his or her face is disposed in the opening 114.

The flotation member of the present application may comprise about any buoyant material capable of supporting a person in a body of water including, but not limited to, a foam mat, polyurethane foam, polystyrene foam, fiberglass, or the like. In certain embodiments, the flotation member may be inflatable. Further, the flotation member may be flexible or substantially rigid depending on the material and application (e.g., how flotation member will be used, the type of water (rough or flat), storage, whether a propulsion system will be used, whether the flotation member will carry equipment, etc.). In certain embodiments, the flotation member is a flexible foam mat that may be collapsed, folded, and/or rolled for storage and transport. The flotation member may also have a friction or non slip surface. The flotation member may also be shaped such that the snorkel system remains stable in the water (e.g., hull shaped). Further, the flotation member may comprise stabilizing components, such as enlarged outer portions, for stabilizing the flotation member in the water.

The flotation member of the present application may be a variety of shapes and sizes. For example, in certain embodiments, the flotation member is configured to support at least about 250 lbs. without sinking. However, the flotation member may be configured to support more or less weight depending on a variety of factors including, but not limited to, the number and size of the people supported by the flotation member (e.g., adults or children) and how the flotation member will be used (e.g., as a full body length member or kick board type member). In certain embodiments, the flotation member has a thickness between about 1 and 3 inches, a width between about 24 and 32 inches, and a length between about 32 and 64 inches. However, the thickness, width, and the length of the flotation member may be more or less depending on a variety of factors including, but not limited to, the size and number of people using the flotation member, the material of the flotation member, and how the flotation member will be used.

For example, the flotation member 102 shown in FIGS. 1A and 1B is a kick board type member. As illustrated in FIG. 1B, the flotation member 102 is sized and configured such that a proximal end 130 of the member is positioned approximately at the waist of the person when the snorkel system 100 is in use. As such, the person's legs are free to kick and guide the person through the water.

As another example, FIGS. 2A and 2B illustrate a snorkel system 200 according to an embodiment of the present application. Similar to the snorkel system 100, the snorkel system 200 comprises a buoyant flotation member 202 for supporting a person in a body of water and a breathing tube 204 having a substantially rigid first portion 206 in fluid communication with a flexible second portion 208. However, the flotation member 202 is a full body length type member. As illustrated in FIG. 2B, the flotation member 202 is sized and configured such that the proximal end 230 of the member is positioned at or near the feet of the person when the snorkel system 200 is in use such that substantially all of the person's body is on the member.

Similarly, FIGS. 3A and 3B illustrate a snorkel system 300 according to an embodiment of the present application. Similar to the snorkel system 200, the snorkel system 300 comprises a buoyant flotation member 302 for supporting a person in a body of water and a breathing tube 304 having a substantially rigid first portion 306 in fluid communication with a flexible second portion 308. The flotation member 302 is a full body length type member. As illustrated in FIG. 3B, the flotation member 302 is sized and configured such that the proximal end 330 of the member is positioned at or near the feet of the person when the snorkel system 300 is in use such that substantially all of the person's body is on the member.

As another example, FIG. 4 illustrates a snorkel system 400 according to an embodiment of the present application. As shown, the snorkel system 400 is configured for use by multiple people. The snorkel system 400 comprises a buoyant flotation member 402 for supporting at least two people in a body of water and two breathing tubes 404 having substantially rigid first portions in fluid communication with flexible second portions. The flotation member 402 is wider than the flotation members 102, 202, 302 such that it may be used by multiple people. Further, the snorkel system 400 comprises a first opening 414 and a second opening 434 extending through the flotation member 402 from the top to the bottom. The openings 414, 434 are sized and configured to permit submersion of at least a portion of the face of a person positioned on the top of the flotation member 402 in the water below the bottom of the flotation member. It should be understood that the snorkel system of the present application may be configured for use with any number of people, including 3 people, 4 people, 5 people, 6 people, or more.

The openings in the flotation member extend through the flotation member and are sized and configured to permit submersion of at least a portion of the face of a person positioned on the top of the flotation member in the water below the bottom of the flotation member. The openings may be any size and cross sectional shape capable of accomplishing this including, but not limited to, circular (e.g., opening 114 in FIG. 1A), rectangular (e.g., opening 214 in FIG. 2A and opening 314 in FIG. 3A), square, and oval (e.g., openings 414, 434 in FIG. 4) shape. The sidewalls of the openings may also be tapered, e.g., tapering inward or outward from the top to the bottom of the flotation member. The opening is generally located between the middle and a distal end of the flotation member. In certain embodiments, the edge of the opening is located approximately 8 inches from a distal end of the flotation member.

The flotation member may comprise one or more handles for the user. The handle may take a wide variety of different forms including, but not limited to, one or more members extending from the top of the flotation member (e.g., a bar or tube), one or more members laminated to the top of the flotation member, openings formed in the flotation member, formed recessed portions on the edge of the flotation member, or the like. For example, the snorkel system 100 illustrated in FIGS. 1A and 1B has a handle 180 extending from the top surface 110 of the flotation member 102 and extending transverse to the longitudinal axis of the flotation member. As shown, the handle 180 is substantially perpendicular to the longitudinal axis of the flotation member 102. However, in certain embodiments, the handle may be at other angles relative to the longitudinal axis or even substantially parallel with the longitudinal axis of the flotation member. Similar to handle 180, the snorkel system 400 illustrated in FIG. 4 has handles 480 extending from the top surface of the flotation member 402. As shown, the handles 180, 480 are located proximate the openings 114, 414, 434 such that it is reachable by the person positioned on the top of the floatation member with at least a portion of his or her face in the water below the bottom of the flotation member.

In certain embodiments, the snorkel system may comprise one or more propulsion systems for propelling the flotation member through water such as, for example, a motor/propeller or jet pump. The snorkel system may also comprise a rudder or fin extending below the flotation member that is operatively connected to a handle such that movement of the handle moves the rudder or fin to steer the flotation member. The rudder or fin may be used with or without the propulsion system, and may be separate from the propulsion system or integral with the propulsion system. Furthermore, the propulsion system may be operatively connected to a handle such that movement of the handle moves the propulsion system to steer the flotation member.

For example, as illustrated in FIGS. 2A and 23, the snorkel system 200 comprises a propulsion system 240 connected to and extending below the flotation member 202 at a location rearward from the opening 214 such that the churned water from the propulsion system does not affect the user's view. A rudder or fin 280 is operatively connected to a handle 242 such that movement of the handle back and forth in a direction M moves the rudder or fin to steer the flotation member 202. The propulsion system may be connected to and extend below the flotation member at about any location. For example, the propulsion system may be connected to and extend below the flotation member at approximately waist level of user.

However, in certain embodiments, the propulsion system (or rudder or fin) is operatively connected to a controller (e.g., a handle, joystick, buttons, etc.) such that manipulation of the controller moves the propulsion system (or rudder or fin) to steer the flotation member. For example, the controller may be mechanically connected to the propulsion system, such as with a flexible member (e.g., wire) or rigid member, such that movement of the controller moves the propulsion system. Further, the controller may be electrically connected to the propulsion system (e.g., with a wire or wirelessly) such that manipulation of the controller will control a motor configured to turn the propulsion system.

For example, as illustrated in FIGS. 3A and 3B, the snorkel system 300 comprises a propulsion system 340 connected to and extending below a forward extension 390 of the flotation member 302 such that the churned water from the propulsion system does not affect the user's view. As shown, the propulsion system 340 is operatively connected to a handle 342 via connection 380 (e.g., mechanical connection and/or electrical connection) such that movement of the handle back and forth in a direction M moves the propulsion system to steer the flotation member 302.

In certain embodiments, the snorkel system may comprise a camera and/or video recorder for capturing images in the water beneath the flotation member. For example, as illustrated in FIG. 2B, the snorkel system 200 comprises a camera/video recorder 250 attached to the bottom of the flotation member 202 to capture images in the water beneath the flotation member. The camera/video recorder 250 may be activated remotely by the person on top of the flotation member 202. Further, the snorkel system may comprise other types of equipment, such as lights, attached to the flotation member.

The breathing tube of the snorkel system generally has a substantially rigid first portion in fluid communication with a flexible second portion. The first portion of the breathing tube extends upward from the top of the flotation member and the second portion is fluidly connected to a mouthpiece. The second portion is sized and configured such that the mouthpiece is accessible to a person positioned on the top of the flotation member and may be inserted into the person's mouth when his or her face is disposed in the opening.

FIGS. 1A-4 illustrate the breathing tubes 104, 204, 304, 404 of snorkel systems 100, 200, 300, 400, respectively, according to embodiments of the present application. The first and second portions of the breathing tubes may be fluidly connected in a variety of different ways. For example, as illustrated in Figure GA, the first portion 606 of the breathing tube may extend into or through an opening in the flotation member 602 and the second portion 608 may be directly connected to the end of the first portion. As illustrated in FIG. 6B, the first and second portions 606 and 608 of the breathing tube are fluidly connected to the opening in the flotation member 602. As such, the opening in the flotation member 602 is part of the breathing system for the person. Connectors 620, such as clamps, nuts, or other fasteners, may be used to secure the portions 606 and 608 of the breathing tube to the flotation member 602. Further, the first and second portions 606 and 608 of the breathing tube may be threadably attached to the opening in the flotation member 602 or form a friction fit with the opening.

As illustrated in FIGS. 1B, 2B, and 3B, the second portion 108, 208, 308 of the breathing tube 104, 204, 304 generally extends from the bottom of the flotation member 102, 202, 302, either from an end of the first portion 106, 206, 306 or an opening in the flotation member, and terminates at the mouthpiece 116, 216, 316 in the face opening 114, 214, 314 of the flotation member such that it is accessible to the user. At least part of the second portion of the breathing tube is submerged in the water during use of the snorkel system. As shown, substantially the entire second portion 108, 208, 308 of the breathing tube 104, 204, 304 is submerged in the water during use of the snorkel system 100, 200, 300. In certain embodiments, the first portion of the breathing tube extends between about 10 and 14 inches above the top of the flotation member (e.g., about 12 inches) and the second portion of the breathing tube is between about 10 and 20 inches long (e.g., about 15 inches).

In certain embodiments, the breathing tube has at least two separate lumens valved for inhalation and exhalation. Air enters the inhalation lumen and exhaled CO₂ exits the exhalation lumen. As such, the user does not continuously breathe in his or her exhaled CO₂. Furthermore, because of the double lumen and the ability of the exhaled CO₂ to escape, the first portion of the breathing tube extending from the flotation member can be longer and permit snorkeling in rougher waters.

For example, FIG. 5 illustrates a breathing tube 500 according to an embodiment of the present application. The breathing tube 500 may be used with any of the snorkel systems described herein. The breathing tube 500 comprises a substantially rigid first portion 506 fluidly connected to a flexible second portion 508, which is fluidly connected to a mouthpiece 516. As shown, both the first and second portions 506, 508 of the breathing tube 500 comprise a first lumen 520, 530 and a second lumen 522, 532. The first lumens 520, 530 are in fluid communication and are dedicated inhalation lumens. The second lumens 522, 532 are in fluid communication and are dedicated exhalation lumens.

The lumens of the first and/or second portions of the breathing tube may comprise valves (e.g., one-way, pressure or demand valves) arranged such that the lumen is a dedicated inhalation and/or exhalation lumen. For example, as illustrated in FIG. 5, the first lumen 530 of the second portion 508 of the breathing tube 500 comprises one or more valves 540 arranged such that the first lumens 520, 530 are dedicated inhalation lumens. Further, the second lumen 532 of the second portion 508 of the breathing tube 500 comprises one or more valves 542 arranged such that the second lumens 522, 532 are dedicated exhalation lumens. It should be understood, however, that one or more valves may be located at various locations in the first and second lumens, e.g., in the lumens of the first portion of the breathing tube. Further, it should be understood that, in certain embodiments, only the second portion of the breathing tube comprises a double lumen.

The flotation member of the snorkel system described herein may be used with or without the breathing tube. For example, the flotation member may be configured such that a user may use flotation member with conventional snorkeling equipment (e.g., a mask and snorkel tube attached to the head of the user) to act as an aid during snorkeling.

FIGS. 7A-7F illustrate a flotation device 700 for snorkeling according to an embodiment of the present application. As shown, the flotation device 700 comprises a flotation member 702 having a top surface 710, a bottom surface 712, and at least one opening 714 extending through the flotation member from the top surface to the bottom surface. The opening 714 is sized and configured to permit submersion of at least a portion of the face of a person positioned on the top surface 710 of the flotation member 702 in the water below the bottom surface 712 of the flotation member. Furthermore, the opening 714 is shaped and configured such that the person may use conventional snorkeling gear, such as a mask and snorkel attached to the head of the user, when positioned on the top 710 of the flotation member 702.

The shape of the flotation member 702 facilitates stability and navigation of the flotation device 700 in the water and waves. For example, As shown in FIGS. 7C-7D, the flotation member 702 is thicker towards the middle where the majority of the weight of the user is placed to facilitate stability in the water. Further, as shown in FIGS. 7C-7F, the bottom surface 712 of the flotation member 702 comprises a curvature and one or more rockers (e.g., front or rear rockers) that help to stabilize the flotation member and facilitate navigation in the water and waves.

The shape of the flotation member 702 also facilitates maneuverability of the flotation device 700. For example, the arrow shaped upper portion of the flotation member 702 creates an area for the user's arms (e.g., to grip) while snorkeling. The indents after the curved upper portion on the left and right sides of the flotation member 702 allow the arms of the user to be free to take pictures, paddle, etc. Further, the lower portion of the flotation member 702 narrows to facilitate use of the user's legs to propel and maneuver the flotation member through the water.

The flotation member 702 may be shaped in a variety of different ways and comprise a variety of other components that facilitate stabilization, navigation and maneuverability of the flotation device 700 in the water and waves. For example, the lower portion of the flotation member may comprise left and right extensions that facilitate stability of the flotation device. Further, the upper portion of the flotation member may comprise left and right extensions that facilitate stability of the flotation device. As shown in FIGS. 7A and 7B, the flotation member 702 is symmetric about the longitudinal axis 718.

The flotation device 700 may comprise one or more handles for the user. The handles may take a wide variety of different forms including, but not limited to, one or more members extending from the top of the flotation member (e.g., a bar or tube), one or more members laminated to the top surface of the flotation member, openings or the like formed in the flotation member, formed recessed portions on the edge of the flotation member, or the like. As shown in FIGS. 7A-7F, the handles 716 are formed as openings or slots through the flotation member 702 and extend transverse to the longitudinal axis 718 of the flotation member. The handles 716 are located proximate the opening 714 such that it is reachable by the person positioned on the top of the floatation member 702 with at least a portion of his or her face in the water below the bottom of the flotation member. In certain embodiments, the handles may be at other angles (e.g., perpendicular) relative to the longitudinal axis or even substantially parallel with the longitudinal axis of the flotation member. Further, the size of the handles (e.g., length and width) may vary. For example, the width H_(W) of the opening forming the handles 716 may be between about 1 and 3 inches. In one embodiment, the width Hw is about 1½ inches.

The flotation device 700 is generally configured to support at least about 250 lbs. without sinking. However, the flotation device 700 may be configured to support more or less weight depending on a variety of factors including, but not limited to, the size of the person supported by the flotation member (e.g., adults or children) and how the flotation member will be used (e.g., as a full body length member or kick board type member).

The thickness, width, and the length of the flotation member 702 may vary depending on a variety of factors including, but not limited to, the size of the people using the flotation member (e.g., adult or children), the material of the flotation member, and how the flotation member will be used. For example, as shown in FIG. 713, an adult sized flotation member 702 generally has a length FM_(L) between about 53 and 57 inches, an upper portion width FM_(UW) between about 28 and 32 inches, and a lower portion width FM_(LW) between about 18 and 25 inches. Further, as shown in FIGS. 7C and 7D, the thickness of the central portion of an adult sized flotation member FM_(CT) is generally between about 5 and 7 inches and the height of the upper portion or nose of the flotation member FM_(UH) is between about 5.5 and 7.5 inches. In one embodiment, the length FM_(L) is about 55 inches, the upper portion width FM_(UW) is about 30 inches, the lower portion width FM_(LW) is about 22½ inches, the thickness of the central portion of the flotation member FM_(CT) is about 6¼ inches, and the height of the upper portion or nose of the flotation member FM_(UH) is about 6½ inches.

As shown in FIGS. 7A and 7B, the opening 714 in the flotation member 702 extends through the flotation member and is sized and configured to permit submersion of at least a portion of the face of a person positioned on the top 710 of the flotation member in the water below the bottom 712 of the flotation member. Further, the opening 714 permits the user to use conventional snorkeling equipment such as a mask and snorkel tube attached to the head of the user. As shown in FIGS. 7A and 7B, the opening 714 is oval shaped. For an adult sized flotation member, the opening 714 generally has a width O_(W) between about 9 and 12 inches and a length O_(L) between about 10 and 14 inches. In one embodiment, the width O_(W) is about 10½ inches and the length O_(L) is about 12 inches. However, the opening may be any size and cross sectional shape capable of accomplishing this including, but not limited to, circular, rectangular, square, and oval shape. The sidewalls of the openings may also be tapered, e.g., tapering inward or outward from the top towards the bottom of the flotation member. Further, in certain embodiments, the opening may not be fully enclosed and may be U-shaped or horseshoe shaped.

The opening is generally located between the middle and a upper end of the flotation member and is generally centered on the longitudinal axis of the flotation member. As shown in FIGS. 7A and 7B, the opening 714 is located in the upper portion of the flotation member 702 along the longitudinal axis 718. For an adult sized flotation member, the edge of the opening 714 is generally located a distance D of about 2 to 5 inches from the upper end of the flotation member 702. In one embodiment, the distance D is about 2½ inches. However, one of ordinary skill in the art would understand that the size, location, and shape of the snorkel opening may vary depending on a variety of factors such as, for example, the size of the person using the flotation device and the type of material used for the flotation member.

The flotation member 702 may comprise about any buoyant material capable of supporting a person in a body of water including, but not limited to, a foam mat, polyurethane foam, polystyrene foam, fiberglass, poly vinyl chloride (PVC), hard plastic, or the like. In certain embodiments, the flotation member may be inflatable. Further, the flotation member may be flexible or substantially rigid depending on the material and application (e.g., how the flotation member will be used, the type of water (rough or flat), storage, whether a propulsion system will be used, whether the flotation member will carry equipment, etc.). The flotation member may also wrapped in one or more materials for wear resistance or strength. For example, the flotation member may be wrapped in a Kevlar to increase rigidity or nylon sheets to increase abrasion resistance.

The flotation member may also have a friction or non slip surface. For example, as shown in FIGS. 7A and 7B, the flotation member 702 comprises slip resistant pads applied to the top surface 710 of the flotation member. The pads may be made of a variety of materials such as, for example, ethylene vinyl acetate (EVA) foam. The top surface 710 may also comprise other friction materials or surfaces. Further, the flotation member may also comprise one or more tethers, rings, or fins. For example, as shown in FIG. 7C, the flotation member 702 comprises an attachment 722 for attachment of leash.

In certain embodiments, the flotation device 700 may be disassembled, collapsed, folded, and/or rolled for storage and transport. For example. FIGS. 8A and 8B illustrate a flotation device 800 having a flotation member 802 that may be disassembled into two pieces. As shown, the flotation member 802 comprises a first portion 840 and a second portion 850.

FIGS. 9-10B illustrate an inflatable flotation device 900 that may be collapsed and folded or rolled for transport or storage. The flotation device 900 comprises a flotation member 902, opening 914, and handles 916 similar to those described above with reference to FIGS. 7A-7F. The handles may take a wide variety of different forms including, but not limited to, one or more members extending from the top of the flotation member 902 (e.g., a bar, tube or other member), one or more members laminated to the surface of the flotation member 902, openings formed in the flotation member 902, formed recessed portions on the edge of the flotation member 902, or the like. As shown in FIG. 9, the flotation member 902 of the flotation device 900 also comprises a leash attachment 960 and a valve opening 950 for inflating and deflating the flotation member. When deflated, the flotation member 902 may be folded (FIG. 10A) and/or rolled (FIG. 10B) for storage or transport. After folding and/or rolling the deflated flotation member 902, the footprint size of the flotation device 900 may be reduced such that it can be easily stored and transported. In one embodiment, the folded and/or rolled footprint of the flotation member 902 is 8×16 inches or less.

In certain embodiments, the flotation member 902 may be made of drop stitch PVC fabric. This material permits the flotation member to be filled to a higher pressure (e.g., between 10-18 psi) than more conventional inflatables made of PVC material. The drop stitch fabric also makes the flotation member hard and rigid when inflated. PVC drop stitch fabric generally comprises sheets of PVC connected together with tens of thousands of polyester threads. The PVC drop stitch fabric of the flotation member may be a variety of thicknesses, e.g., 75, 100, 120, and 150 mm. As shown in FIGS. 9-10B, the flotation member 902 comprises a 75 mm thick drop stitch PVC fabric. However, the flotation member of the present application may also comprise other materials including non-drop stitch PVC material. In certain embodiments, the PVC material of the flotation member may be covered with Kevlar to increase the rigidity of the flotation member.
